"Better" is a subjective opinion, barring side by side comparison, and I haven't yet seen a documented case of anyone doing so. But from a theoretical standpoint if the T36 is built with a 26 inch wide mouth it will have the same mouth area as the Lab, and therefore the same potential extension and sensitivity, while the box would still be 5 cubic feet smaller than the Lab. The T36 horn path at 8.5 feet supports full horn loading to 33 Hz, so the additional path length of the Lab is not of benefit since your desire is to go to 32 Hz. Below the flare frequency the T36 operates in direct radiator mode, the Lab doesn't, so the T36 extends deeper when only a few boxes are used. The T36 can be built using a variety of drivers, either 12 or 15 inch, either one or two, while the Lab is driver specific to one model that has had some problems. As for throw, with the same approximate mouth area there is no reason for either one of the other to have an advantage. The only theoretical advantage for the Lab is extension below 20 Hz and then only if at least 8 cabs are clustered to get the necessary mouth area.
The graphs I've seen of the T36 slim show half-space 1m/1w response. Graphs I've seen of the Lab also show half-space 1m/1w response, and they aren't a whole lot different. McBean sims of the two also show the same thing. The two designs are definetely different, but the jury is still out on which, if either, is better.
